Description
Technical field
The present invention relates to a kind of safety element, be particularly related to a kind of safety element that is used for banknote, this safety element has carrier material and magnetic code (magnetic code) and/or based on the independent code (hereinafter being called conduction code conductivity code) of electric conductivity, and additional light code (opticalcode).The invention still further relates to a kind of security credence (security clocument), particularly a kind of banknote with safety element.Specifically, safety element is a kind of security thread (security thread).Security thread extensively is used in the various different products as security feature, especially in the loan (security papers).A kind of known application that must satisfy high demand for security is the security thread that embeds in the bank note, and light code has in most of the cases constituted just (positive) or the negative printed words (negative writing) that can with the naked eye check under transmitted light.The light code can substitute the code by the Optical devices check, maybe can be a kind of additional code, particularly a kind of bar code (WO 99/28852).
Background technology
In order to prevent to copy security thread, security thread also has other security feature usually except the light code, the coating that particularly has conductive cladding and/or have magnetic characteristic, described coating be set at other layer above.This security feature is checked by machinery, so also be referred to as " mechanical features (machinefeatures) ".The light code is made of mechanical features itself usually, and the method for formation is to make relevant coating form positive printed words or form negative printed words by the corresponding gap in coating.The conventional method that forms the light code is that metallized silk is carried out the part demetalization, thereby remove layer (EP0748896A1) simultaneously with magnetic characteristic, or the deposition have magnetic characteristic layer, so that not with demetallised regions mutual interference mutually, perhaps form this layer very thin, although the layer so that be magnetic, the demetallised regions of security thread also can be by visual identity (EP 0498186A1) under transmitted light.
Do not adopt to make the mode of security thread vacuum metallization processes produce conductive layer, can be applied with the printing-ink of metal coloring yet to conductive cladding, as silver bronze (EP 0516790B1, Fig. 8).In addition, also can utilize the mixture of carbon black granules to make the magnetosphere conduction, thereby can just can form all three kinds of security features simultaneously, be i.e. magnetic, conduction, negative writing feature by printing an individual layer.
In addition, using the layer with magnetic characteristic in the mode that forms special code also is known (EP0914970A2).Described magnetic code can or can form (EP 0610917A1) by the material that magnetoresistor detects by magnetic material, code can detect to be not only because the local distribution of material, but also because different magnetoresistive characteristics (EP 0610917A1), or different magnetic layer thickness (EP 0914970 A2) or different magnetic characteristics, as remanent magnetism or strong stupid characteristic (WO 99/28852).
In addition, from WO 99/28852, as can be known, not only can adopt the magnetic coating of special code form, but also can produce special conduction code by in determining section, using conductive metal layer.
If need not see under transmitted light bright dipping code, magnetic coating can have for example utilizes the corresponding literal of traditional oils ink print on magnetosphere, to replace the gap (EP 0610917A1, EP 0748896A1) of negative printed words form.
Usually said security thread is the silk with existing mechanical features that the forger that hides can not recognize.But because magnetic code has and the different overall appearance of conducting metal coating of being with metallic luster usually, thereby this is not easy to be avoided.
Therefore, WO 99/28852 proposes in the mode of alignment (exact register) magnetosphere and conductive metal layer to be set with piling up, thus make they hidden fully each other (conceal).This method only could success when only observing security thread from a side or having an opaque baseplate material at least.For the security thread in the banknote, its light code of test under transmitted light, but security thread is normally transparent, so owing to observe the side difference, the result can present different outward appearances.Under the visible situation in security thread both sides, EP 0516790B1 and EP 0748896A1 propose to cover fully with conductive material the both sides of magnetic coating, thereby can form same outward appearance on paper under reverberation and transmitted light.
EP 0914970A2 has adopted different hidden methods.The document proposes, come " sheltering " magnetic bar code by the bar (masking bar) of sheltering that the same magnetic material is provided in the zone between magnetic strips, this bar of sheltering only is being different from the bar that constitutes magnetic code on the thickness of material thereby on the intensity of magnetic feature.Like this, because at first glance can imagining, the forger who hides shelters the part that bar is a magnetic code, so optically hoodwinked.But the quality of production of security thread must satisfy with the quality that is used for the measurement mechanism of test safety silk can discern the very high requirement of sheltering bar reliably, and does not depend on magnetic code.
Summary of the invention

In the accompanying drawings, the material of identical layer is without exception with identical Reference numeral representative.
Fig. 1 represents the negative style element (negative text element) 1 of the magnetic code of continuous conduction.That is, light code 20 is that the gap that constitutes character in the continuous conduction coating 30 by safety element 1 forms.Safety element 1 is made of transparent plastic 10, and like this, if safety element 1 for example is embedded in bank note or the another kind of security credence, light code 20 is visible under transmitted light.
Print special magnetic code 40 on the coating 30 continuously, the optical appearance of the coating 30 below magnetic code is with the naked eye undistinguishable.Magnetic code 40 for example can form bar code.Under the simplest situation, described code can be continuous coating, just as the continuous conduction coating 30 in the present embodiment.
In such a way, impartial observer is unaware of safety element not only light code 20, and also has magnetic code 40.According to the present invention, because " magnetic code " has the special magnetic material properties that is used for detecting by magnetic properties the safety element authenticity, so " magnetic code " refers to any " magnetic coating ".Thereby this coating also can be for example to be confirmed and can be distinguished the material coating that comes with other material of safety element by magnetoresistor.
The safety element of Fig. 1 has three kinds of security features, i.e. light code 20, magnetic code 40 and continuous conduction 30.Therefore be " triple code ".Certainly, if coating 30 without any special physical characteristic and for example be a kind of neutral printing-ink, purpose of the present invention also can realize.The most basic condition that coating 30 should satisfy is can not differentiate the material of magnetic ink 40 from optics.
Fig. 2 represents the similar safety element 1 with Fig. 1, and it, but is covered with magnetic ink 40 as carrier material 10 continuously by transparent plastic, and this magnetic ink covers with the special code of electrically conductive ink 30 again.This safety element need not special magnetic code and is adopted special conduction code 30, and this safety element does not have continuous conduction, and possesses continuous magnetic.Opposite with the safety element shown in Fig. 1, light code 20 is not only in the continuous magnetic coating 40 of safety element 1, but also in the zone of conductive cladding 30.Because light code 20 is negative printed words, in view of the above, magnetosphere 40 and conductive layer 30 all form the gap in the zone of light code 20.In the present embodiment, the also available neutral printing-ink of magnetic coating 40 substitutes continuously, but this will make the security feature quantity of safety element reduce to two from three.
The observer is also hidden especially with the forger who hides owing to improved security, so this preferred implementation of the present invention provides three kinds of security features, a kind of optics, a kind of magnetic, a kind of security feature of conduction, described security feature forms with the unresolvable cladding material of optics, and with the form of printing-ink by suitable method, preferably printing technology, be applied on the safety element 1.Printing technology for example is serigraphy, intaglio printing, lithographic printing and aniline printing, and preferably serigraphy and intaglio printing.Certainly, also can use other suitable method, form security feature as spraying or evaporation coating technique.If the employing evaporation coating technique preferably uses the vacuum coating method.
